I'm looking to get a used laptop but I can't decide which one to get. They're all priced pretty close at around a grand but the XPS 15 L502X is $100 cheaper. I narrowed it down to these 3:

Alienware M15x

XPS L702X

Which one would you choose? Would you go for the better CPU or better GPU? Are these a good price at around a grand each?
Any suggestions or comments would be greatly appreciated.

Thanks in advance!

Go with the Dell XPS L702X, the Graphics card is better then the others. It ranks 61st for laptops, while the Alienware ranks 66, and the other Dell ranks 111.

Also, it got pretty good specs allround, you'll be happy with it
